If God judged us based on what we deserve, we would all be in trouble! That is why the psalm writer begs, "do not deal with us according to our sins." We all rely on the mercy of God, but Jesus brings in a new twist for us to think about. "For the measure with which you measure will in return be measured out to you."
One more thing: Christ gives us a corollary to the great commandment in today's gospel. Loving others as we love ourselves includes forgiving them as we want to be forgiven. The next time you find the kids in the kitchen underfoot, get out the measuring cups. Ask them how much forgiveness they want from God, and teach them that's how much they have to show to others.
Prayer: Father in heaven, thank you for your infinite mercy. Help me to be generous in my forgiveness. Amen.
